ATX style connector
Replacement for the older P8
and P9 AT style connector, this connector connects the computer power supply to an ATX style motherboard. As shown to the picture to the right, this 20-pin multicolor cable often labeled as P1
connects to a 20-pin connector on the motherboard. Note, with the introduction of ATX-2, this cable is now a 24-pin cable and no longer a 20-pin cable.
As also seen in the picture to the right and below, the cable has a small clip on the top of the cable that should snap and hold the cable in place when installed properly. This cable is also keyed, which means it can only be inserted in one direction.
